Journalists posted to the House of Representatives on Monday observed a touch screen, intended to display the legislative body's schedule for the current day, showing porn.

The touch screen, located just outside the press room, displayed a free video porn site. House staff, internal security and reporters tried to close the site, but their efforts came to no avail. It appeared that the porn site was airing from an external source.

This is the second time the House's internal security has been breached this week.

Previously, senior actor Pong Harjatmo was able to climb on to the House's roof to paint messages on it.
